Pneumocystis carinii (P. Carinii) has emerged as the leading opportunistic pathogen and a major cause of mortality in AIDS. P. carinii and AIDS have been attracting the interests and attention of many researchers all over the world. Studies of P. carinii by many methods and different ways have important significance. The paper reports for the first time the effect of the emitted qi on P. carinii infected Wistar rats.

1. Adult female Wistar rats weighing 150-200g were divided into A(26), B(28), C(26) groups randomly. Group C was the control one.

Two qigong masters emitted their qi to Groups A and B for 15 minutes each time once every other day, 7 times altogether. Then P. carinii Pneumonia animal model was built up by a regular method. The rats received a standard treatment regimen of cortison acetate. 25 mg, injected subcutaneously twice a week, low protein (7%) diet, and tetracycling in rat's drinking water until examination. After drug treatment started, the rats were treated by the emitted qi for one week . They were examined 4-8 weeks after the drug treatment.

The experimental results suggested that the body weight of the 3 groups decreased, but this was more obvious in the control group. Table 1 shows the difference of the infected rats among the three groups. About the carinii infection rate see Table 1.

For differentiation of infected degree.see Table 2. It shows the difference of the infected degree of P. carinii among the three groups.

The lung smears from the three groups were stained by Giemsa. It was found that the parasites were the typical P. carinii. Table 3 shows the differences of the sizes of P. carinii cyst among the three groups.

The experimental results suggest that the emitted qi reduces the infection rate and degree of Wistar rats by P. carinii. The emitted qi can inhibit the infection of P. carinii.

2. Nude mice were divided into two groups. Group A (10) was injected with (5-8)X10exp-2 parasites by lung innocubation. Group B were injected with parasites which had been treated by the emitted qi. The parasites were put into a small glass. A qigong master emitted his qi to the parasites 20 minutes and altogether 4 times. Each interval lasted for 48 hrs.

The experimental results showed that 10 mice of Group A were infected by PC, in which 4 mice were of moderate infection degree, but in Group B only 6 mice were infected by PC, and all were of light infection degree. Two groups had big difference.
